gh-98894: Check readelf failures in test_dtrace (GH-152345)

Report readelf command failures directly instead of later failing with
missing-probe assertions.
(cherry picked from commit d60a677)

Co-authored-by: stratakis <[email protected]>

* gh-98894: Fix DTrace test_check_probes for shared builds (#151122)

When building with --enable-shared, the SystemTap/DTrace notes
live in libpython. Add detection logic to be used by readelf.

Force the C locale on readelf output.

(cherry picked from commit 3a08e93)

* gh-151496: Use process groups in test_dtrace (#151512)

Create a new process group to run bpftrace commands, so it's possible
to kill also child processes on timeout.

(cherry picked from commit a064b32)

* gh-151496: Use process groups in TraceBackend in test_dtrace (#152039)

Run the generic DTrace/SystemTap commands in a new process group and
terminate the whole group on timeout.

This prevents a forked tracer child from keeping stdout/stderr pipes
open after the direct tracer process is killed.

(cherry picked from commit 1785f4b)

* gh-98894: Check readelf failures in test_dtrace (#152345)

Report readelf command failures directly instead of later failing with
missing-probe assertions.

(cherry picked from commit d60a677)

* gh-98894: Check tracer exit status in test_dtrace (#152893)

Fail functional dtrace and SystemTap cases directly when the tracer exits
non-zero.

(cherry picked from commit 311e7e7)

* gh-98894: Quote test_dtrace tracer subcommands (#152901)

Use shlex.join() when building tracer -c command strings
for avoiding issues with spaces.

(cherry picked from commit a159c68)

* gh-98894: Fix dtrace tests in shared builds (#153372)

Generate SystemTap probe definitions targeting libpython for shared
builds and use centralized USDT probe object discovery for readelf
and BPFTrace.

(cherry picked from commit 298bef3)

* gh-156703: Set LD_LIBRARY_PATH in SystemTap trace commands (GH-156424)

Prefix commands passed to stap -c with LD_LIBRARY_PATH via env, when
probes reside in libpython. This allows the interpreter to find
libpython when staprun does not preserve the loader path.

(cherry picked from commit faf4e52)

* gh-156722, test_dtrace: Terminate tracing processes gracefully on timeout (#156753)

Send SIGTERM to the tracing process group before falling back to SIGKILL.

(cherry picked from commit 55ecc0a)

* gh-156701: Increase the SystemTap usability timeout (#156720)

SystemTap may compile a kernel module during its usability check
(if no cached module is available). We need to allow a larger timeout
for that case.

(cherry picked from commit e1be613)
